RSS Integration to Automatically add links

[codingmatty]

Is your feature request related to a problem? Please describe.
I use LinkWarden as a sort of reading list of articles that I receive from various emails and I would love to bypass the manual step of receiving the email and adding the link to my LW instance.

Describe the solution you'd like
I would like to add RSS feeds to automatically save and archive articles to read later. Preferably, with a default category setup.

Describe alternatives you've considered
I tried getting TT-RSS setup and was going to try to connect it to the LW API, but I gave up after an hour or so of trying. I've also thought of trying with FreshRSS or just setting up a small little custom server, but it just seemed like a natural feature that could be added to LW.

Additional context
I'm happy to work on it myself. I've already start ideating on how to fit it into the LW architecture, reusing the batch worker to fetch the RSS links. Regardless, I'll probably do this for my own instance.
